Definitions

  • This invention relates to a sheet treating apparatus for use in a recording apparatus or the like for recording images on sheet film.
  • a laser imager for recording on film an image signal obtained by the use of a diagnosing apparatus such as CT or MRI
  • the image signal inputted is first modulated into the intensity of a laser beam, and then this laser beam is applied to the film and the film is sensitized in conformity with the density of the image to thereby effect recording.
  • the sensitized film is developed by a developing apparatus, whereby an image having light and shade conforming to the image signal is obtained on the film.
  • film having silver salt emulsion applied thereto is sensitized with intensity conforming to an image to thereby effect recording, and the film is subjected to the so-called wet type developing process in which the film is immersed in developing liquid and fixating liquid for a predetermined time to thereby effect a developing process.
  • Such a wet type developing process uses chemical liquids such as developing liquid and fixating liquid and is therefore cumbersome in treatment. Also, these chemical liquids become deteriorated and unusable when a predetermined process is carried out and therefore, it is necessary to interchange them suitably. The chemical liquids after used need be disused, and there is the inconvenience that the waste liquids produced at such time cause environmental problems.
  • FIG. 10 of the accompanying drawings shows the construction of a laser image using such a dry type silver salt system.
  • a supply magazine 2 and a receive magazine 3 are provided in parallel in a recording apparatus 1 , and an optical unit 4 for applying a laser beam L downwardly is provided above the receive magazine 3 .
  • a heat developing apparatus 6 having a developing roller 5 is provided on the left side of the recording apparatus 1 , and this heat developing apparatus 6 is formed with an opening 6 a for discharging film F therethrough.
  • the solid line in FIG. 10 indicates the conveyance path of the film F.
  • the unrecorded film F in the supply magazine 2 passes along the conveyance path and recording by the laser beam L is effected on the film F below the optical unit 4 . Further, this film F is conveyed to the heat developing apparatus 6 , is developed by the developing roller 5 and is discharged from the opening 6 a in the heat developing apparatus 6 .
  • the film F is heated and developed while being twined around the developing roller 5 , and this also leads to the problem that the film F becomes curled.
  • the present invention has as an object thereof to find out optimum disposition relationship between units to thereby provide a compact and highly accurate sheet treating apparatus and method.
  • One preferred form of the sheet treating apparatus has containing means containing a plurality of sheets therein, recording means for effecting recording on the sheets, a substantially straight path for conveying the recorded sheets, and heat developing means for heat-developing the sheets in the path, and is characterized in that the containing means and the recording means are disposed under the heat developing means.
  • Another preferred form of the sheet treating apparatus has containing means for containing a plurality of sheets therein, recording means for effecting recording on the sheets, a substantially straight path for conveying the recorded sheets, and heat developing means for heat-developing the sheets in the path, and is characterized in that the containing means and the straight path are disposed so that the straight path and the sheets in the containing means may be substantially parallel or substantially orthogonal to one another.
  • a preferred form of the film treating method of the present invention is characterized in that recording is effected on film at a recording position and the recorded film is heat-developed above the recording position without being curled.
  • FIG. 1 shows the construction of a first embodiment of the present invention.
  • FIG. 2 is a plane view of an optical unit.
  • FIG. 3 is a cross-sectional view of the conveying roller of a developing portion.

  • FIG. 10 shows the construction of an example of the prior art.
  • an image recording apparatus 11 has its interior covered as a dark space with a cover 12 , and an opening 12 a for film F to pass therethrough is formed in the upper portion of the cover 12 .
  • the interior of the cover 12 is partitioned by partition walls 13 and 14 to thereby prevent a light beam having entered the opening 12 a in the cover 12 from further entering the interior.
  • the partition wall 14 is formed with two openings 14 a and 14 b for the air to flow therethrough.
  • a removably insertable supply magazine 15 containing piled unused films F therein is contained horizontally in the cover 12 .
  • This supply magazine 15 is formed with an opening 15 a for taking out the films F therethrough.
  • a lid portion 16 for opening and closing the opening 15 a is attached to the supply magazine 15 so that when the lid portion 16 is closed, the supply magazine 15 may have its interior kept as a dark space.
  • Each film F has only its underside formed into a silver salt emulsion surface, and a latent image may be recorded by a minute laser beam being applied to the silver salt emulsion surface, and by this latent image being developed, an image can be formed to thereby accomplish recording.

  • the scanning angle ⁇ of the rotatable polygon mirror 32 is too great, the shape of the laser beam L will be varied by the influence of the aberrations or the like of the optical system or the deviation of the focus of the optical system will become great and therefore, it is preferable that the scanning angle ⁇ be of the order of 30 to 40 degrees or less. Accordingly, when for example, film F of 35 ⁇ 43 cm is mainly scanned in the direction of 35 cm and the effective width W of this film F is 33 cm, the distance A of the path along which the laser beam L reflected by the rotatable polygon mirror 32 passes until it arrives at the film F is about 45 to 50 cm, which is equal to or greater than the length of the film F in the direction of movement thereof.
